OK . . . I'm an XP user.
Sonar X-1 has run great on my XP box (with obvious limitations), but I can take the Cakewalk hint . . . dont' upgrade to Sonar X-2 on XP.
No . . . they're not going to get my upgrade money right now, but when I inevitably buy my Windows 7 box, eventually they will get my upgrade money. Technology moves, no escaping that. The Cakewalk idea to abandon XP support had to happen sometime.
I watched Sonar Seth's video about the X-2 changes. I like it. I want it . . . but all that new complicated software programming can't happen with Win Xp's 3GB RAM limitation. End of story. Some of the best songs ever written were on 4 track tape machines, but that's gone too.
